Now I see what you mean. My rims (unknown manufacturer) don't seem to have the roll (for want of a better term) that provides a hook for the trim ring. I can see why you have to pry yours off, while mine slide on and off with only a little effort.

Are the teeth on my rings customary, or are yours attached some other way? What I'm getting at is that if all rings attach similarly, I'll remove mine and live without them. Hello, eBay?
